This invention relates to a multi-support portable electric lamp and the primary ob ject of my invention is to provide a spot light that may be easily and quickly attached to a suitable support or placed on a support to cast a beam of light in a desired direction. Such a lamp may be advantageously used for reading purposes or in a window for illuminating an object, for instance a time clock in a jewelry store window.

Another object of this invention is to provide a compact portable electric lamp with a hollow base containing a clamping instrumentality by which the base may be attached for a bedstead, chair or other support to hold the lamp convenient to reading purposes. The same base includes a hanger bywhich the lamp may be supported at a right angle to a wall and these clamping and hanging instrumentalities are concealed within the base, when not in use, so that the base may be set on a table to support the lamp thereon.

A further object of this invention is to provide an electric lamp housing with an air cooled reflector, a spot lens and a color screen. The air cooled reflector prevents the lamp housing from being excessively heated. the spot lens will cast a beam of light and concentrate the light on a desired spot, and the color screen may be advantageously used for a lighting eiiect or display purposes.

The above are a few of the objects attained by the durable and inexpensive construction to be hereinafter specifically described, and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a front elevation of the lamp showing the base in cross section;

Fig. 2 is a side elevation of the lamp showing the base and lamp housing in longitudinal section;

Fig. 3 is a bottom plan of the lamp base;

Fig. 5 is a longitudinal sectional view of the lamp housing showing an air cooled reflector, and

Fig. 6 is an elevation of a lamp housing having a plurality of lenses. a

A lamp comprises a hollow base 1 and screwed or rotatably mounted centrally of the top of the base is a stem 2 provided with a pivot mounting 3 for a conventional form of electric lamp socket 4 provided with an incandescent lamp 5; i y

The stem2'and pivot mounting 3 are tubular or hollow so that a leading-in conductor 6 may extend from the base 1 upwardlyinto the socket 4L and the electric circuit for the lamp 5 is controlled in the socket 4 by a conventional form of switch finger piece 7. The leading-in conductor 6 may extend through an insulator 8 in. the. rear side wall of the base 1, and said leading-in conductor does not interfere with any swivel or turning movement of the stem 2 on the base 1 or pivotal movement of the lamp socket at the pivot mounting 3, which may be fixed by a clamp ing screw 9 to hold the lamp socket at a de sired angle relative to'the perpendicular or thebase 1. v

Mounted on the lamp socket): is a lamp housing 10 having a rear wall 11 provided with vents 12 so that air may enter the housing for cooling the walls thereof and a re doctor 13 placed against the rear wall 11 of the housing. The front end of the housing 10 is'closed-by a detachable front wall or lens holder 14 provided with a spot'lens 15 held in engagement with the holder 14: by resilient clips 16. and 17 The clip 16 may frictionally engage the housing 10 to hold the lens holder in a closed position, while the clip 17 may engage in an opening 18 of the housing'lO and serve as a pivot 01' hinge connection for the lens holder; whereby it may be swung downwardly to an open position-and supported by the lamp housing 10. The lens15' cooperates with the lamp 5 and the reflector 1 1n prov1d1ng a beam of light that may be projected in a desired direction by adjusting the lamp socket 1 relative to the base 1.

In some instances the front end of the housin may be provided with a color screen 18 attached by lugs 19 or other fastening means to a frame 20 frictionally fitted on the front end of the housing 10.

In lieu of the reflector 13, I may use a perforated hood shaped reflector 21 which may be mounted on the lamp socket 4 to inclose the lamp 5. This hood shaped reflector may be in spaced relation to the housing 10 to provide an air gap 22 for cooling purposes. (See Fig. 5.)

Instead of one lens the housing 10 maybe shaped to support additional lenses as shown in Fig. 6.

The base 1 is of such configuration that it may be placed on afltableto afford a substantial support for the lamp and within the base are instrumentalities for clamping or hanging the base relative to a support. Opposed side walls of the base 1 have inwardly projecting studs 23 and on these studs are the coiled portions 2 1 of'a resilient yoke shaped clamping member 25 that may be swung out of the base and placed in engagement with a support 26 to clamp the base 1 against the support, whereby the lamp may be supported at substantially a right angle to the support 26 or at any position to which it may be adjusted by virtue of the pivot mounting 3 or the rotatable mounting 2.

The studs 231also serve as a support for the ends 27 of a wire hanger QS and this hanger canbe swung out of the base 1 to suspend the base 1 from a nail or-the like placed in a wall or other support. It is now there are three ways of supapparent that with the two adjustporting the lamp and ments it. is possible to conveniently use the lamp for various purposes.

Obviously there aremany designs for the lamp base 1, the housing 10 and the pedestal portion between the base '1' and the housing 10, and I preferito make these harmonizeas much as possible so that there is a neat and attractive structure.

In combination with a hollow la a pa r of studs carried internally by bi a wire yoke adapted for concealment withiri sa d base and having its sides coiled around said studs and its ends abutting said base whereby said yoke has a yielding relation to sand base, and a wire hanger within said base having 1ts ends looped around said studs.
